I have switched the BF3 card to NIC mode and compiled the DPA_all_to_all sample on the Host (x86), but it fails to run. However, it runs correctly on the DPU (Arm). How can I run it on Host(X86)?

Hi,

The error “Kernel failed to issue general PRM command=0x100, errno=EPROTONOSUPPORT” typically indicates that the kernel or driver does not support the requested PRM command.

Please wait for the upcoming Doca-3.2 version which will be released at 25.10, this issue will be fixed.

Thanks!
